Payment Plan Math in Oklahoma
Under Oklahoma law, the maximum interest rate on a payment plan is set at 6 percent per year, as provided by 15 O.S. § 266. This statute governs the legal rate of interest when a contract does not specify a different rate or when the law otherwise applies. The 6 percent figure applies to judgments and certain overdue obligations unless the parties have agreed in writing to a higher rate permitted by statute. The official text of the statute, available through the Oklahoma Legislature’s website, details how this rate is calculated and any exceptions. The worked example below illustrates how the 6 percent figure is applied in a typical payment plan scenario. Use the DocketMath calculator to estimate your own specific payment plan figures under this rule.
